Three new Cu(I) π-complexes with 2,5-bis(allylthio)-1,3,4-thiadizole (Bialtia) ([Cu 3 Cl 3 (Bialtia) 2 ] ( 1 ), [Cu 3 Cl 3 (Bialtia)] ( 2 ), and [Cu 2 Cl 2 (Bialtia)] ( 3 )) are obtained by the alternating current electrochemical synthesis and studied by single crystal X-ray diffraction. A distinctive feature of Bialtia is its ability to coordinate to Cu(I) atoms by nitrogen atoms of the thiadiazole core and two allyl groups. The formation of island inorganic {Cu 3 Cl 3 } moieties occurs in 1 through π coordination of two independent Bialtia molecules by three metal atoms. Due to the absence of one Bialtia molecule in 2 , inorganic {–Cu 3 Cl 3 –} subunits join into infinite chains {[Cu 3 Cl 3 (Bialtia)]} n }. The structure of [Cu 2 Cl 2 (Bialtia)] ( 3 ) contains two Cu(I) atoms with different coordination environments: distorted tetrahedral and trigonal.
